To all w/wm'it may concern: 1

Be t knownthat I, FIAL R. STAFFORD, a citizen of the United States, residing at North ,Plainfieldfln the county of Somerset .and State ofNew Jersey, have invented cer-v -t'ain new and useful Improvements in Invisible Cab-Turrets, of which the following The first of the objects of this invention is the provision of. a device of the character the locomotive cab as is done with the ordinary arrangement of cab turret.

A further object of the invention is the provision of a convenient -'arrangement of V j apparatus whereby the auxiliary valves may tion.

be placedupon the outside shell of the boiler and operated from within the cab while at the same time removing all the piping from the locomotive cab. I

A further object of the invention is the provision of one'or more manifolds placed within the boiler shell supplied by dry pipes from the dome and constructedwith a reinforcing plate riveted to theoutside of the shell to compensate for the weakening of the shell thatwould be otherwise caused by the tap holes provided for the valve connec A. further object. of thi'sinvention is the PI'OVl'SlOII of a device which will insure a much better location ofthe steam supply valves attached to the turret and which will afford jmuch greater safety to the engine crew and protection against danger of scalding on account of the knocking ofl? of the turret or partsv and the escapement of steam in case of accident.v j

Still another object of this invention is the provision of an arrangement which can be mostadvantageously used in export locomotives inasmuch as'it will be unnecessary with this device to remove the cab turret in shipping the boilers without cover. The apparatus also can be made more cheaply than those heretofore employed and will be more serviceable in use.

The above as well as such other objects as may hereinafter appear I obtain by means of a construction. which I have-illustrated.

Figure 1 is a side view of a portionof an pa'irof turrets shown in Fig. 3. Fig. 5 is a 7 INVISIBLE can-Truman 1 Specification of Letters Patent. 5 Patented Oct. 4, 1921. Application filed November 17, 1919. Serial in; 338,634. r

a the line 2+2 of Fig. 1; Fig. 3 is a plan view of the device shown in Figs. 1 and 2; Fig. 4

is a-plan view of a modified. arrangement employing but a single turret in place of the diagrammatic plan view of an arrangement employing a pairof turrets located in front of the forward wall of the cab with operating rods extending. laterally and backward and connecting with actuating handles located within the cab whereby all of the iping may be arranged -up0n the outside 0 the cab and yet ready' access' obtained through the operating valves by handles accessible to -the engineer "or fireman ;within the oal). V Fig. .6 is aside elevation of the turret casing itself and Fig. 7 an end view of the same.

Referring now more particularly to Fig. 1, it will be seen that I have therein shown a cab 1 having a roof 2 broken-away in orderto expose-to view the interior within which I have indicated: in sectional view, the' introduction of the interior turret casing 3 secured to the top sheet of the boiler as shown by means of a. plurality of rivets 4.- extending through'fianges 5 there being a forwardly extending nozzle or projection 6 which is connected at '7 with a dry pipe coming back from the steam dome of the locomotive or other'convenient source of supply.

As will be clear from examination of Figs. 1 and 2, theturret casing 3 is located upon the interior of the boiler shell with certain of the adjacent crown sheet rods or bolts 8 passing through they flange to aid in securing the parts in place, and there is provided upon the outside of the boiler shell a plate 9 which reinforces the shell and provides compensating strength as against theweakening effects of the apertures formed in the shell by the connection of the supply pipes thereto. Various outlets from the turbe used for other purposes common on locomotives.

As shown in Figs. 6 and 7, the turret casing 3 is formedofsheet metal bent into the shape indicated and preferably welded along the line marked 12 in Fig. 7 which,

being upon the inner bend or curve, will not be subject tothe same? tendency to breakage or opening at the seam as would be a joint along the opposite side. It is tobe observed that the pressure on this device 'is fundamentally greatest upon the outside wherefore there shouldbe no difiiculty with the welded form shown. This condition also obtains with regard to the position of the flange with relation to the boiler shell .so that it is not essential to use a verylarge number of rivets to insure a tight omt 1n fastening the shell to the turret casing, and the provision of the outside plate 9 is more for stiffening the metal of the shell f-and strengthening the device to compensate vfor the weakening effect of the pipe con-v nections than from need of obtaining a tight steam joint. Y

Referring particularly to Fig. 5, it will be seen that I have therein indicated a pairof inside turrets located forward of'the front wall 13 of the cab and having the valves connected by universal joints indicated at 14 at opposite ends of the rods 15'and a r ranged to be actuated .by'the handles 16 within the cab. By this arrangementall the piping and connections may befdisposed outside the cab and still have-the valve device's actuated 'from handles convenient of access upon the interior of the cab as will be readily apparent.

I claim: 1. A locomotive boiler having a steam turret secured upon the inside of the boiler 2. A turret forsteam boilers having a valve ,for controlling' said outlet "located upon the outside of the boiler shell; 5

3. A turret located uponflthe inside of the boiler shell, a supply valve upon the outside of the boiler shell communicating with said turret, and a strengthening plate upon the outside of said boiler shell with means for securing the plate andturret together.

, 4.' A turret located upon the inside of the boiler shell, a supply valve upon the outslde of the boiler shell communicating with said turret, and a strengthening plate upon; the

outside of said boiler shellwith means for securing the plate and turret together, said means comprising a plurality of rivets pass- ,ing through the flange of the turret and the plate. V o

A turret located upon the inside of the boiler shell, a supply-valve upon the outside of the boiler shell communicating-with said turret, and a strengthening plate upon the outside of said boiler shell with means for securing the plate and turret together, said rmeans comprising a plura'lityof rivets, and

a plurality of stay bars. o r

6. A turret locatedupon the inside of the boilershell, a supply valve upon the outside turret, and a strengthening plateupon the of the boiler shell communicatingf'with said outside of said boiler shel-l with means for securingthe plate and turret together, said means comprising a plurality of rivets, and

a plurality of stay bars, the turret being located between adjacent rows of said stay bars.

7 In a boiler,the combination of a steam turret located therein, a steam supply pipe from the turret extending through the boiler shell, and means for icontrolling the supply through said pipe. V

In testimony whereof, I have hereunto signed my name.
